Application May 24, 1950, Serial No. 163,909

4 Claims. (Cl. 30-40) This invention relates to improvements in razors.

It is an object of the invention to provide an improved form of razor,which is adapted to automatic blade changing.

A further object of the invention is to provide such a razor havingimproved mechanism for separating the blade holding elements so as torelease the blade.

In my prior application, Serial No. 159,038, filed April 29, 1950, forimprovements in Razors and Blade Magazines Therefor, I have disclosed arazor and automatic blade changer operable therewith, the razor beingarranged for opening by means of projections on the guard which passthrough apertures in the back to engage a razor support in the bladechanger. The present invention makes provision for opening the razorwithout requiring such projections on the guard of the razor.

With the foregoing objects in mind, as well as others which will appear,the invention consists in the combinations and arrangements of partswhich will now be described with reference to the accompanying drawingand then be pointed out more particularly in the appended claims.

ln the drawing:

Figure 1 is a front elevation view of a razor embodying the invention ina preferred form of embodiment and showing the same in position in therazor holding means of a blade changer;

Figure 2 is a view similar to Figure 1 with the razo: and magazinesremoved;

Figure 3 is a section on line 3-3 of Figure 2;

Figure 4 is a section on the line 4--4 of Figure 1, showing also the boxof the blade changer;

Figure 5 is a side elevation of the razor.

Figure 6 is a back elevation of the razor; and

Figure 7 is an end elevation of the razor.

The razor comprises a handle 1, in which there are riveted or otherwisesecured, a back 2 and a spring 3. A ferrule 4 may be provided, the partsbeing conveniently held together by a rivet passing through all fourelements. A guard 6 is held against the back 2 by the spring 3, asindicated. The back 2 has an angularly disposed flange forming a cap 7and the blade B is held between this cap and the guard, as indicated.The blade is held accurately in position by means of lugs S at the endsof the guard, and the spring 3 working against the guard and pushing thesame toward the back also pushes the blade back under the cap andagainst the angle of the back, as shown in Figure 5. Since the blade isengaged by the lugs 8 only at its ends, which are beveled slightly asshown, practically the entire cutting edge is available for shaving. Theguard is held in position on the back by projections 10 passing throughapertures 11 in the back, as shown, and the back is provided withapertures 12 for accommodating projections on the blade changer, ashereinafter described.

The mechanism for accomplishing the blade change is not shown herein andmay be any -suitable mechanism such as is shown and described in myapplication above referred to. In the present application, there is2,700,214 Patented Jan. 25, 1955 ICC shown only the mechanism forholding the razor in position for a blade change. This mechanismcomprises a plate 17 arranged to hold magazines 15 and 16 for new andused blades respectively, by means of projections 19 and otherarrangements (only part of the plate and magazines being shown in thedrawing). The plate is formed with upstanding iange like elements 20,which are bent over slightly so as to hook over the cap 7 of the razorwhen the razor is held upon the plate 17, and

0 with projections 23 adapted to pass through the apertures 12 in theback of the razor for forcing the guard upwardly as shown'in Figure 4.The back of the razor is held down flat against the plate 17 by a springclip 21 which goes through opening 22 in the back of the razor and hooksover the edge of this opening. By these means, the razor is securely andfirmly held in position on the plate, with predetermined relation to themagazines held thereby and the guard and back of the razor are separatedso as to permit a blade change by sliding a new blade into the razor inalignment with the used blade therein so as to push the used blade intothe used blade magazine.

What is claimed is:

1. The combination of a razor and a holder, the razor comprising a back,a guard and means for yieldably holding them together in blade holdingrelation, the back comprising a portion for overlying the blade and asupporting portion attaching the same to the handle and disposed at anangle to the first said portion, and the holder comprising a support,means for holding the supporting portion of the back of the razor downon the support and means for engaging the guard to force it away fromthe back and release the blade when the back is so held on the support.

2. The combination of a razor and a holder, the razor comprising a back,a guard and means for yieldably holding them together in blade holdingrelation, the back comprising a portion for overlying the blade and asupporting portion attaching the same to the handle and disposed at anangle to the first said portion, and the holder comprising a support,means for holding the supporting portion of the back of the razor downon the support and projections on the support for engaging the guard toforce it away from the back and release the blade when the back is soheld on the support.

a. The combination of a razor and a holder, the razor comprising a backhaving an aperture, a guard overlying the aperture, and means foryieldably holding the back and guard together in blade holding relation,and the holder comprising a support, means for holding the back of therazor down on the support and a projection positioned to pass throughthe aperture and engage the guard to force it away from the back andrelease rthe blade when the back is so held on the support.

4. The combination of a razor and a holder, the razor comprising a backhaving a pair of apertures, a guard overlying the apertures, and meansfor yieldably holding the back and guard together for holding a bladewith the apertures equidistant from the blade and from its ends, and theholder comprising a support, means for holding the back of the razordown on the support and projections positioned to pass through theapertures and engage the guard to force it away from the back andrelease the blade when the back is so held on the support.
